Styling Changed

Hi folks,
I developed my screen using expo, and it was working fine in expo projects.
But when I generated the APK using expo, the syling of a component was changed.
Can anyone help?
Here’s my code.

{this.state.show ? ( ) : null} {" "} {this.state.stop ? "Pause" : "Resume"}{" "} navigate("Timer")}> Back

const styles = StyleSheet.create({
container: {
backgroundColor: “black”,
position: “absolute”,
top: 0,
left: 0,
right: 0,
bottom: 0,
justifyContent: “center”,
alignItems: “center”
},
scrollContainer: {
backgroundColor: “black”,
position: “absolute”,
top: 0,
left: 0,
right: 0,
bottom: 0,
justifyContent: “center”,
alignItems: “center”,
height: “125%”
},
landscapeImages: {
height: “85%”,
width: “90%”,
alignSelf: “center”,
position: “absolute”,
top: 0
},
countDownStyle: { position: “relative”, alignSelf: “center” },
buttons: {
// flex: 1,
position: “relative”,
flexDirection: “row”,
top: 20
},
landscapebuttons: {
position: “absolute”,
bottom: 0,

flexDirection: “row”
},
